摘要：

The influence of Cr concentration on the corrosion resistance of Fe73.5Si13.5B9Nb3Cu1 metallic glass in simulated marine atmospheres with chlorides (Cl-) was studied. Cyclic polarisation measurements were carried out to study susceptibility to localised corrosion. All the tests were carried out with the same material in different states: amorphous, nanocrystalline and crystalline. DC current electrochemical techniques were used to analyse the corrosion kinetics. Gravimetric tests were used to establish the reliability of the data obtained electrochemically. The study also focused on the modification of the magnetic properties in the material as a result of exposure to an aggressive medium and Cr addition. (C) 2002 Elsevier Science Ltd.
